You could also do the following: draw the profile of the Morph (if it is a revolved Morph) using an Arc or Arcs. Then, when you define the profile for the Revolved Morph, create that curved profile out of 4 or 6 curved Morph segments. Then define the revolution axis and angle as usual.
Because you create the profile out of several curved segments the resolution of the Morph body in effect will be that much greater (since each curved segment is approximated with linear segments) and you will achieve a smoother surfaces.
You can then make hidden those lines of the generated Morph you don't want to see displayed.
This seems to be a better solution than simply doubling the segmentation level because the latter creates up to 10 times as many polygons for the Morph body and still does not achieve the level of smoothness achieveable with the above method.
